T5 lighting

[nickb]

I'm setting up a 60G cube tank for seahorses which will include some seagrasses. I had planned PC lighting but have been told this might not be enough for the seagrasses. As an alternative, I was considering T5 (to avoid the heat production I would get from an MH pendant).

I was trying to reserach the usefulness of T5 for this setting (e.g. would 4x24W bulbs be a better lighting source for seagrasses in a 24" deep tank than 3x55W PC?)

Also, I was looking for information about pre-built T5 units which are available in Canada without having to buy from the US. My search of my usual vendors hasn't revealed anything except DIY parts.
